INCUBATOR.

Specification of Letters Patent.

Pateutd March 19, leo?.

J ularly specifying the novelty.

This invention relates to the care of live stock, and more especially tothat class of de-l vices thereunder Known 'as' incubatorsf and theobject of the same is to produce an incubator, with a hinged orremovable cover, wherein the flues shall be so arranged as to radiatethe heat from a common center (above the heater) to the corners of theincubator-casing, the better to serve the objects in view.

-To this end the invention consists in a central location for the heater(herein shown as a lamp) and the employment of a cover (herein shown ashinged) beneath which the flues are arranged, with a hood for receivingthe products of combustion from the lamp or the heat from the heater,directing it into said iiues, causing it to iiow radially outward to thecorners of the casing, and permitting it to escape into the air at thosepoints.

The following specification describes the present embodiment of myinvention, reference being had to the accompanying drawings, in which-Figure l is a perspective view of the incubator complete. Fig. 2 is asectional view of the same with the hinged cover raised'. Fig. 3 is asection on a diagonal line through the casing, as shown in Fig. 1.

Referring to the drawings, the letter B designates the body of theincubator, mounted on legs or supports S, and the heater or lamp li isshown as supported by said supports centrally beneath the body B. In thepresent instance the heater is a lamp whose chimney extends upward intothe body and almost through the same, as shown.

The egg-tray E mayhave any convenient location, and the other detailsare not ampli- 'lied in the drawings, asthey form no part of y thepresent invention.

C is a cover, in the present instance hinged, as at H, although it couldbe entirely removable without departing from the idea in view.

y This cover may have glass panels G, permit.- l ting inspection of theeggs and trays. lossitly it has a transverse central strip, as of wood,W within its frame; but such details are not important.

Coming now more particularly to the present invention, the letters Fdesignate tlues extending radially and diametrically from the center ofsaid cover O outward to its corners, where they are upturned oryotherwise communicate with outlets O, as shown. At the center of thecover, where these flues converge, there is a`hood or tubular member F,communicating with all said flues, possibly thermostat (such as T,indicated only in outline) and having its lower end open and largeenough to iit over the upper end of the heater (in this case alamp-chimney) when the cover is let down or put in place, so as toreceive therefrom the pro ducts of combustion which are directed intothe several ues and by the latter passed over the eggs tothe severaloutlets O.

It will be obvious that when the cover is raised or removed thethermostat T goes with it; but when it is in place the thermostatperforms its usual functions.

It is considered unnecessary to amplify and illustrate other details ofthe incubator, though it is probable that some regulator for the heaterwill be employed other than the thermostat herein referred to. Theshape, size, materials, and proportions of parts are not essential, andconsiderable change in and amplification of the construction set forthcan be made without departing from the spirit of the present invention.It appears to be only necessary to say that the heat rising from theheater'passes into the hood and from the latter is deflected in X shape.over and above the eggs, finally finding its exit at the corners throughthe outlets O.

What is claimedas new is l. In an incubator, a casing, acentrallydisposed stationary heater within the casing, a hinged coverfor the latter having outlets at other points than its center, a hood atthe center thereof adapted to fit over the heater when the cover isturned down into place, and flues carried by the cover and connectingsaid hood with the outlets.

2. In an incubator, the combination with l a casing, and a heaterdirected upward having its upper end open and regulated by a through thecenter of the casing' cover for the casing having t central trans- Versestrip and corner-outlets, a hood supported by said strip and extendingthrough the cover wherebyT it is adapted to i'it over the heater, andilues carried by the cover and leading from the hood to the outlets.

3. In an incubator, the combination with e. casing, and a heaterdirected upward through the center of the casing; of a Sover for thecasing comprising a frame with outlets in it and a central transversestrip, it hood carried by seid strip and adapted to 'lit over saidheater when the cover is closed, and lues carried by and and connectingsaid hood with said outlets, as and for the purpose set forth.

4. In an incubator, the combination with ot a hinged. :t casing, and estationery i l l heater ldirected upward through the center of thecasing; ot :L hinged cover tor the casing haring outlets nt its corners,:t central hood carried by und opening through the cover :rnd adapted to'tit over said heater when the cover is closed,

e thermostat on the cover for controlling the beneath the cover heutflowing 'from said hood, und ilues cau'- ried hy and `lrxeneirth theCover and lending from seid hood to seid outlets, -for the purpose setforth.
